We're implementing an android application that needs to collaborate with the fingerprint sensor. After any installation of the application, a login page will prompt and the user must add a username along with fingerprint.

I read something about that the applications can't collaborate with the fingerprint sensor. However, I thought maybe someone has an idea.

Thanks in advance.

UPDATE:
The thing that prevents me from achieving that is the BiometricPrompt which gives a true/false state. I need the exact value of a fingerprint and send the data to the server for a specific username.

  • what exactly is your question ? – a_local_nobody Jan 16 '20 at 13:01
  • You can try `BiometricPrompt` for fingerprint [check here](https://medium.com/mindorks/fingerprint-authentication-using-biometricprompt-compat-1466365b4795) – Jahanvi Kariya Jan 16 '20 at 13:02
  • @a_local_nobody Authorize a user on an android application with a fingerprint instead of a password. In addition, the fingerprint data isn't stored on a particular phone, it stored on a server. – M. Rostami Jan 16 '20 at 13:04
  • what is preventing _you_ from achieving that ? what have you tried ? – a_local_nobody Jan 16 '20 at 13:05

  • you should update your question to make that more clear, if you're specifically trying to get the fingerprint that should be added to your question – a_local_nobody Jan 16 '20 at 13:10
  • @a_local_nobody Just updated. So, can I accomplish that? – M. Rostami Jan 16 '20 at 13:14
  • i'm not sure :) but your updated question will find answers hopefully – a_local_nobody Jan 16 '20 at 13:15

    no problem, you should always try to include what you've done and what's preventing you from achieving your goal in your questions, otherwise it sounds like you simply want code as a solution and haven't tried anything. i hope you find an answer now :D – a_local_nobody Jan 16 '20 at 13:20

So if you want to store user information with their credentials and their fingerprint then it's not possible.

Fingerprint data will never be shared with anyone. Google has strict guidelines
